120 mm case fans represent the best mix of size and importance in air cooling. These fans typically connect via 4-pin or 3-pin power connectors and can have many characteristics (such as slim models, lighted up with LEDs, etc.) to meet your different needs. Because computers create heat and your internal components are prone to get hot while running, it's important to use case fans to move that heat away from your sensitive hardware and out of your system. With our selection of 120mm case fans, the right pc fan for you is just a few clicks away. Take your pick from our selection of 120mm fans from top brands like Corsair, Noctua, Cooler Master, AeroCool, Antec and more.

FAQ & Section Info
What 120mm fan should I buy?
120mm case fans are one of the more common sizes for computer fans. They are supported by nearly all ATX and Micro ATX cases, and can provide a good amount of CFM with high RPMs, and many have low noise features to keep your system from sounding too much like a Huey. If you aren't too concerned about noise levels, there are plenty of low cost fans with high RPM and CFM to move the air in and out of your case with little fuss. But if you're looking for features like energy efficiency and quiet running then you'll probably be looking for a bit higher quality fan with a more specialized bearing than ball bearings, maybe something a Hydro-Dynamic Bearing (HDB) fan, and a 4-pin fan with Pulse-Width Modulation (PWM) to only use the energy necessary to keep your hardware cool.
